The FDA is considering approving an experiment to repair a genetic disease in humans by creating embryos with DNA from three parents. Genes would be transferred from a healthy human egg to one that has a disease and the “repaired” egg then fertilized in the hope that a healthy baby will result. The goal of the experiment in genetic engineering is not a perfect baby but a healthy baby.
In my view, trying the technique to fix a terrible disease even with risks of failure makes ethical sense. The FDA may ask for more studies in monkeys, but that really wont settle the safety issue in humans. Given the severity of mitochondrial diseases it is worth trying the technique.
